The steepest vineyards in the world are located in Switzerland.
Answer: False.
The steepest vineyards are located in Germany between the villages of Bremm and Eller on the Mosel River. The Calmont vineyard, whose name roughly translates to rocky mountain, was carved by the Mosel more than 400 million years ago, and has been planted with grapes for more than 1500 years. Calmont’s 60- to 70- degree incline makes it look like a vertical wall of vines, all tenaciously gripping the slatey cliff.
